Weapons rain from the sky in alternating directions, and contrary to popular belief, this attack is NOT a reskin of arrow rain. As opposed to the arrows, the weapons rain from left to right and right to left when cast.

A Barbarian was made as a collectible figurine along with the 4 main knights.

The Beefy Barbarian seen at the start of the battle is one of only four Beefy Barbarians seen in the game. Besides this one, there is the one who kidnaps one of the princesses in the Barbarian War level (possibly the same one due to how close they are in location), the one in the Necromancer boss battle (which still could have been the first one as well as he is undead) and lastly the one who sells the Thick Sword at the Swamp Store.

Barbarian is a C Rank character. (C)

He is a star head skin in Battleblock Theater.

You could play as Barbarian and Blue Knight for a limited amount of time in Happy Wars.
